Charleville floodwaters peak below estimates

Residents in the south-western Queensland town of Charleville are relieved the worst of the flooding appears to be over.

But authorities are still warning flash flooding is possible from heavy rain expected in the region overnight.

Forty-two people are spending the night in an evacuation centre in Charleville after Bradley's Gully peaked this afternoon at 2.1 metres.

That was well below the predicted 3-metre peak.

Four businesses were affected, but dozens of homes were spared.

Murweh Mayor Mark O'Brien is hoping the heavy rain holds off through the night.

"Plenty of things to do tonight and a fairly big morning tomorrow. It just never ends this sort of stuff, the Gully is still up at two metres and we still have people in the evacuation centre we want to see," he said.

Councillor O'Brien says locals were given enough warning and the situation is much improved.

"Very grateful to the bureau for their warnings early in the piece and we've learnt that they usually give us very good guidance," he said.

"We think the worst of it is over."

A temporary flood barrier will be installed in Charleville tomorrow. Flood gates on the town's new levy are not due to be finished until next month.

Weather warning

"There's a chance of seeing some areas well over the 200 millimetre mark," he said.

Premier Anna Bligh says extra resources have been sent to the town in case of more heavy falls.

"We've sent extra police to Charleville, we've sent extra swift water rescue teams out to Charleville, we're talking regularly to the council and we're keeping the people of Charleville very much in our thoughts," Ms Bligh said.

The Charleville Showgrounds pavilion has also been opened as an evacuation centre.

Authorities have already had to help one man out of floodwaters.

Police Inspector Mick Dowie has urged locals to be sensible.

"If you don't need to be out there it'd be good if you could just go home and free up the roadways, get your kids out of the water," he said.

Downstream preparations

Emergency workers were also preparing to sandbag homes at Surat, south of Roma, in the state's southern inland.

Surat is preparing for the Balonne River to hit 10.4 metres, although it is unlikely to inundate homes.

The Paroo River at the tiny town of Eulo, west of Cunnamulla, is still rising and expected to peak at major flood levels on Wednesday.

Four homes have been evacuated as a precaution and authorities say they are hoping the river does not exceed the 2010 flood level.

Major flood peaks are also expected in the towns of Thallon, Nindigully, Fenton, Dirranbandi and St George later in the week, as flows from the Moonie and Condamine-Balonne system move south.

In north-west Queensland, major flood levels are also occurring in the Flinders and Cloncurry rivers.
